Great Liveaboard for an amazing place

Cocos is the best diving I have ever done. Sharks (a lot of) on every dive. The staff, food, activities and just everything proposed lives up to the high expectations that is Diving Cocos Island.

Extraordinary

The crew was super friendly and helpful. Everyday fresh and super delicious food.
The dive sites were selected by the national park, therefore it can happen that you dive several times at the same site but no dive is like another.
The dive guides were experienced and taking care of the divers very well.

Unbelievable trip best staff I've ever experienced diving both live aboard and land based.

Where would one begin? My first whale shark in 30 years of diving, or maybe the dive where simultaneously we had a huge Manta ray two hammer heads three Galapagos Sharks a Large Tiger shark and a two hundred pound Tuna rolls through.
Every meal was a highlight as was the entire staff perfect organization. Without question the best live aboard ive done. That starts at the top nice reflection on the Captain.

Fantastic trip to Coco's island

The raw wildlife and nature on Coco's island were stunning. Every night there was a beautiful sunset. Also the service of the staff was incredible! Every time we got out of the water they distributed fresh fruits and towels. During our first dive of the day the staff always checked our rooms and cleaned the toilets. I also liked that they made a video of the whole trip which we could purchase additionally. This was our first liveaboard and we enjoyed it so much! Thank you guys!

Less hammerheads, great service

It was January so we didn’t see large schools of hammerheads but we did see plenty of them, and tigers and even mantas and silver tips. Food was excellent and the level of service on the boat and when diving was fantastic. All the staff were great. Dived a variety of sites. I thoroughly enjoyed the experience.

Excellent service; average to good, way below expectations diving experience

The experience onboard is one of luxury, down to the detail. The crew are extraordinary in looking after customers' safety and wellbeing, providing a superior quality service. The boat itself is somewhat aged, though she does the job, that is to take you safely to Cocos and back, sleep and feed you, very well. The diving part of the trip was overall good, though my expectations were way higher for a once in a lifetime, bucket list diving cruise to Cocos. Perhaps we chose the wrong season, or maybe the water was too warm (read: less bumpy sailing), but we missed on those big numbers of pelagic exemplars. Considering the needed time investment, the cost of the cruise, all obligatory extras and gratuities, in hindsight I'd reprioritise this experience over other dates, or destinations. The support received from Liveabord was, as usual, impeccable.

Nice diving, best crew.

For the price of this liveaboard and the park fees (500$), I suggest to go only in winter season, with better currents and much more marine life. Divemasters can push harder to find marine life instead taking pictures to sell to divers at the end of the trip. Anycase, exceptional service of all staff and incredible destination.

Okeanos Agressor I is a nice and confortable boat. Coco Island is like in the movies and it's very pleasant to have opportunities to explore it a little bit.
We were lucky enough to see all the big stuff under water.

The two favourite dive sites - Dirty Rock and Punta María - and the night dives has offered me a magic that i will never forget. The island is intact, true nature, the sky is full of shiny stars. On the top of this the staff is really professional and ready to serve the guest with the highest possibilities with a big smile.

Trip of a lifetime

The diving was incredible, one of the best places in the world to dive hands down. The food was plentiful and of high caliber, there was almost too much too eat. The crew was very hospitable and catered everything almost too well. The captain needs to realize that this trip is for the costumers and getting in the way with his huge camera while diving was an inconvenience. Although, his photos are amazing and I am happy that he provided them to us. But when a client is having an amazing experience with a Tiger shark, Hammerhead, Galapagos etc. the last thing they want is to have someone move in front of them (or their camera) to get a better shot.

Diving wirh the sharks was one of the most incredible and rewarding experiences of my life.

Diving with the hammerheads, white tips, and rays. Being in the ocean experiencing and being part of the ecosystem. And feeling safe thanks to Warren and the other dive masters. Also seeing the dolphins surrounding the panga on one of the dives. The food and service was excellent.

amazing liveaboard adventure

Great trip. I'm already planning the next one to a different point in Costa Rica.
The only drawback has nothing to do with the Okeanos: seemingly due to national politics, the park fee to Cocos Isl has doubled two years ago to roughly $500.There has been a lot of grumbling about this. Thus, I won't be going back to Cocos until, hopefully after the next prime minister's election, this policy is amended to a more reasonable price.
